Do you watch screencasts?

I’ve discovered this way of getting technical information for myself only recently. Impression is only positive so far - the perceptual speed is much faster comparing to reading.

For example, after Coding in Objective-C 2.0 I can write a program in this language using classes and have an idea how the memory management works in Objective-C (by the way, it’s quite interesting concept - a “manual” garbage collector when memory is freed automatically but the programmer has to manage the counter of active links to an object by himself.

Currently watching Writing Your First iPhone Application and the next is Erlang in Practice.

This is a delicate moment with screencasts - it should be made qualitatively. Otherwise it’s waste of time.

Which screencasts do you watch? What can you recommend?

P.S. By the way, I like The pragmatic Bookshelf online store more and more. All books are in multiple DRM free formats (pdf, mobi, epub).
